Counting from December 16, 2021
Those 1,742 days include roughly 249 full weeks and about 5 complete years. The difference between the rounded figure and the exact one matters here: dividing 1,742 by an average year length gives 4.77 years, while walking real calendar months gives 4 years, 9 months and 7 days. Both answer slightly different questions, so both are shown above.
